Regenerative braking plays an important role in improving the efficiency of electric vehicles. But excessive regenerative torque may affect the anti-lock brake control. The paper presents a novel brake control strategy for electric vehicles which integrates the regenerative brake control and anti-lock brake control. The strategy is designed based on a novel idea called "slip trial method", where the regenerative brake torque and the friction brake torque are coordinated according to the slip of driving wheels. The strategy depends on neither road condition identification nor longitudinal braking force estimation. Simulation studies show that the strategy can obtain almost the optimal regenerative brake efficiency, and the tire slips are regulated in the stable region.

Evaluation of the impact toughness of film is important in predicting the performance of a material in applications such as packaging, construction, and other uses. The test simulates the action encountered in applications where moderate-velocity blunt impacts occur in relatively small areas of f...
